Aren’t revolvers sort of semi-automatic? The mechanism revolves to the next chamber.

No gas pressure from the last round fired in a revolver turns the cylinder to the next round. Your finger does that.

Interestingly there was an automatic revolver (semi-auto) made see

Excellent point. The Striker 12 & Streetsweeper are not autoloaders but merely revolving shotguns with a windup spring assist.

In the current frenzy any Remington 1100 could be banned just like they did in Australia (banned Remington 870s, too).

No, revolvers are not semi-automatic. Their chambers are all pre-loaded. In a semi-auto, the chamber actually empties and is automatically reloaded ready for the next shot. A revolver has 6 chambers that all start loaded and cannot be reloaded without manually removing the cartridge and replacing it, while with a semi-auto, you replace the magazine and the gun does the work to load the cartridge in the chamber.

I get your point but semi-auto refers to the loading of the cartridges, not just the ability to fire a second or third time with each trigger pull.
